Functor

In category theory, a functor F is an operator on types.

F is also considered to be a polymorphic operator on functions with the type

F : (a -> b) -> (F a -> F b).

Functors are a generalisation of the function "map".

The type operator in this case takes a type T and returns type "list of T".

The map function takes a function and applies it to each element of a list.
